> Also libfontconfig is not on its RUNPATH:

Indeed, all the ‘openjdk’ packages have fontconfig has an input, but
‘guix size openjdk | grep fontconfig’ shows it’s not there, meaning that
nothing actually linked against fontconfig.

Perhaps we should patch this ‘fontpath.c’, with ‘substitute*’, so that
it refers to libfontconfig.so by its absolute file name?

Thanks,
Ludo’.
